Help what is it?

Does anyone recognise this plant? My Sister gave me some seeds from the plant growing on her friends wall apparently it’s a climber and is as tall as the house before I plant it I think it would be wise to find out what it is. It was in the garden when the friend moved in!

Thank you spritzhenry for your suggestion but it is not, the answer was under my nose all the time!
Would you believe it. I am reading Carol Klein ‘Life in a Cottage Garden” Page 86 there is a photo of my little plants at exactly the same stage they are Ricinus communis ! it belongs to the euphorbia family, a sub-tropical plant. I phoned my sister and asked what aspect the plant on her friend’s house was … south facing in a sheltered spot consequently, it has grown to a height of 15 feet It’s not a climber after all more of a perennial.

Hi Spritz.. I have been reading up on them. I have seen that they are toxic, not so good. I plan to put them at the back of the border well away from harms reach (the grandchildren). Have you grown them before? From the pictures I’ve seen they look spectacular.
Well I think this is the opportunity for a bit of friendly competition. Who can grow the tallest! Although, if they grow above the garden fence hacksaw hubby may have to be let out of his study. (He's just started another OU course so he will leave my garden alone for the rest of the summer.....I hope!).
